Hold the Line

‘From Fromelles to the final advance — war as it was lived, in the words of the men who faced it.’

One battalion. Three years of war. Ordinary men under relentless pressure.

‘I was eighteen when I was first sent into battle at Fromelles… War is both the silliest and cruellest activity that a man can get mixed up in. It breaks my heart even now to think of it.’

— Walter Herbert ‘Bert’ Bishop, 55th Battalion

In 1915, news from Gallipoli stirred tens of thousands of young Australians to enlist. They trained for a campaign that ended before they reached it. Their war would be fought elsewhere — in the shattered fields, sodden trenches, and ruined villages of France and Belgium.

Hold the Line tells the story of one of those units: the 55th Battalion of the Australian Imperial Force. Raised from volunteers and shaped in the camps of Egypt, the battalion was sent into the grinding, industrial warfare of the Western Front — a war of mud, machine guns, and relentless attrition.

Drawing on letters, diaries, and firsthand testimony, Tim Cook traces the battalion’s journey from the disaster at Fromelles through the hard fighting at Polygon Wood, Péronne, and Bellicourt. These are not distant battle reports, but the voices of the men themselves — young soldiers struggling to endure fear, exhaustion, loss, and the daily uncertainty of survival.

By the Armistice in 1918, more than 500 of the 3,000 men who served with the 55th Battalion were dead, and another 1,000 wounded. Those who lived through the war carried it with them for the rest of their lives.

Though centred on a single battalion, Hold the Line captures the shared experience of Australian soldiers on the Western Front. It is war as it was lived — close, exhausting, and unforgiving — and a lasting tribute to the men who endured it.

‘A vivid and unflinching account of Australians at war on the Western Front.’

‘War as it was lived — close, exhausting, and unforgiving.’

‘A powerful battalion history grounded in firsthand testimony.
